Joining up!
We don't have our trip booked yet, but will be going something like July 2-12 or 3-13 or 4-14, something to that effect. We probably won't be able to book until mid-Feb (you know, tax refund time)
Grandma4ever, backing up about 4 pages, we flew out of Kansas City on Southwest last year, I'm a couple hours east of you. They don't post their flights as early as the other airlines do, I noticed a couple of days ago that they don't have July in their system yet, I think they only go 6 months in advance so it should be soon. They do have some direct flights. Might be cheaper to fligh AirTran but we wanted a direct flight-- first time flying with DS11 and DS8 (autism) and we weren't in the mood to make it complicated, the airports themselves are enough crazy without a layover.
Southwest also doesn't do seat assignments. You go to their website 24 hours in advance (I think) and print a boarding pass that gives you a spot in line. I went to the website at exactly the right minute and we hit somewhere in the 50's in line and no problem getting the seats we wanted. However, the flight there was awful-- but not their fault exactly-- both kids wanted a window seat so DH & I split up and sat in adjacent rows, which left the aisle seats open. DH got some cool guy who sat yapping about GameBoys with them. I got the Meth Addict.

Seriously. Took off her shoes, fell asleep talking to herself and wiggling around, and couldn't be woken up. DS had to go to the bathroom and I couldn't wake her up. DH got out of his seat, and lifted our kid
over this chickie, dragging his feet, didn't wake her up. She slept thru
landing, almost slid off her seat. It would have been funny if it wasn't so awful.
So you know, Southwest does have that reputation, of not attracting, shall we say, the highest-level clientele

but they're usually the cheapest. I suspect we'll be using them again.
Oh yes, and LuvMySoldier, have you thought about hooking your DBF up with the flag retreat at Magic Kingdom? DH did it last year and it was by far the coolest thing we did the whole vacation. It's just really really neat, very moving.
